Nearly 6,000 marijuana plants with a street value of about $5.9 million have been seized on Kaua'i, state and federal law enforcement officials announced this morning.

The "largest outdoor growing operation ever prosecuted in Hawai'i" was discovered at the foot of Mount Wai'ale'ale in the area referred to as the "Blue Hole," officials said.

Five people, including a convicted federal felon, have been arrested and charged with manufacturing with intent to distribute more than 1,000 marijuana plants as a part of "Operation Green Stream," officials said.
